The truck consistently flashes a warning for -??Service Antilock Brake System-?? and a scanning tool provides the code C0020-01. The truck was evaluated at a local mechanic, who indicated the code represented a general ABS system failure. I have researched the issue and found that this problem is a common complaint with 2018 Ram 2500s.

In July, I drove over a bridge expander bump and now I am getting two errors: 1) Service anti-lock braking system with the ABS light on; 2) Service electronic brake system with the traction control light lit. The lights and notice come on then go off for a few minutes then back on again. This repeats until I turn the truck off and restart it. It then stopped for several months, but is now doing it again yesterday after driving over a very small bump in the road. My vehicle is available for inspection upon request. This problem puts me and my family at risk because the anti-lock braking system and traction control are deactivated during these incidents. I am not able to reproduce the problem at will, it happens randomly and intermittently. The vehicle has not been inspected yet. On-line research indicates many owners are having to replace ABS sensor and pump around the same amount of mileage as mine.

My ABS and traction control light intermittently blinks on and off. I took my vehicle to the dealership and was told this is a known issue. That I need a new ABS power module and controller. The parts are very expensive and on back order. I was informed to continue driving the vehicle until the parts are available.

The ABS and Traction Control lights constantly come on, even after replacement HCU and ABS parts are replaced. It-??s a once a year fix, and should be recalled. Once the lights come on, braking is affected, and cruise control no longer functions. I used a previous date, because I need to replace the parts again, for the third time. I have asked Ram support to just send me the parts, and I will do the repair, but unfortunately, they prefer that I continue to pay the dealer to repeat the same repair over and over.

Electronic Braking System and Anti-Lock Braking System has intermittent failure and any speed. The safety of those in the vehicle are at risk by unsafe braking and unpredictable braking. Warning signals turn on and off while driving. Started to appear around 44,000 miles.

The abs and traction control light are flashing on and off SEVERAL times especially when on a rough road. It kicks my cruise off and sometimes stays on which locks the diff and disengages any ABS functions resulting in the loss of braking performance and capability.

The contact owns a 2018 Ram 2500. The contact stated while driving at an undisclosed speed, the brake pedal was depressed but the vehicle was slow to respond or stop. The ABS and traction control warning lights were illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the hydraulic control unit needed to be replaced. The vehicle was repaired under the warranty, but the failure recurred. The service electronic stabili-trak message was displayed. The vehicle was taken to an independent mechanic; there was a hard code retrieved: COO2O-O1; related to the ABS pump motor control. The manufacturer was not contacted. The failure mileage was approximately 21,477.

At approximately 30,000 miles the vehicle warning lights for "Service ABS" and "Service Electronic Brake System" began flashing intermittently. I took it to the local dealer and they replaced the Hydraulic Control Unit (HCU) on 5/12/2021. Approximately 2 months ago the exact same warning lights began flashing again so we took it back to the dealer yesterday 9/28/2023, 53,000 miles, and they diagnosed it as being the HCU and recommended that we do not drive the vehicle. They want to charge me for the exact same repairs that happened 23,000 miles ago. This issue is known but yet they will not fix this vital safety component of the vehicle. I cannot believe that a recall has not been initiated for this safety hazard.

ABS and Traction Control code warning lights appear intermittently on instrument panel stating -??service electronic braking system-?? and -??service ABS system.-?? These indicators flash consistently on the IP but do not stay constant currently. Failure of these systems could result in loss of control of the vehicle during emergency breaking by allowing the tires to lock up during breaking. Code has been verified by Champion Chrysler Jeep in Brighton Michigan as -??ABS Pump Motor Control.-??

I have approximately 86000 miles on my truck and today the Service Electronic Brake system warning starting coming on and off. Along with the ABS light and traction control light. Randomly flashing on and then off. Staying off most of the time. I did a search and apparently this is a huge issue with these trucks, a couple of electronic assemblies melting together and going out. This needs to be a recall that Ram pays for. What happens if my brakes go out?

- Wichita Falls, TX, USA

ABS/HCU modules have failed. A loss of ABS and braking power have been experienced. When towing, this creates a problem as it happens very suddenly and intermittently, placing myself and others at risk of loss of braking power. Warning lamps indicating ABS failure/electronic braking system service is needed come on only when braking, and is intermittent. There is no indication of a problem until brakes are applied.

I have a 2018 Dodge Ram 2500 pickup truck and my ABS engine light came on back in February 2023 indicating that I have a problem with my braking and traction control system. It was because of the Hydraulic Control Module was bad. I Contacted a Factory Chrysler Parts supplier to obtain a new part to have it replaced but they were on backorder until June. In June I contacted them again and was told they were on back order until October 2023. I just contacted them again 9/27/23 and now I am being told the part is on back order until February 2024. This will be a full year causing me to drive without the ABS or Traction control not working, as well as not having cruise control. Doing a search on the internet there are a lot of others having the same issue which is bad enough but when you can't even get the replacement part for over a year on a piece of safety equipment for your vehicle. This is more then a safety issue.
